Full Of Assasin
When ***********, replace Endless Battle or Rose Gold Meteor with Skypiercer. You can also buy Skypiercer early if you feel you will win the lane and snowball.
Assasin Tank
This emblem is suitable for use as an Assassin and offers a little defense.
Battle Spell
Use this spell as a finisher to maximize the use of the execute spell. The spell's cooldown will be reduced by 40% if used and successfully kills an opponent.
Before level 4, Grock won't be at his best, so just play a hit-and-run game.
In the early laning phase, don't be too aggressive, and gather exp and gold until level 4 and have purchased some damage items. If you have, you can immediately cause trouble and attack the enemy brutally.
Best With Zilong
Zilong is very weak in the early game and doesn't have a dash skill, which makes it easier for Grock to defeat Zilong.
Watch Out For Phoveus
Phoveus is very strong in the early to level 4 or even in the late game, so Phoveus can counter the hero Grock.
